Browserbase MCP

What Browserbase MCP does

Browserbase MCP connects MCP-compatible agents to a Browserbase cloud browser. The browser is driven by Stagehand, while the MCP interface presents browser operations as tools that an agent can call.

The server covers the main lifecycle of a browser session: an agent can create or reuse a session, work with a web page, collect information from it, and close the session when finished. This makes it suitable for browser automation tasks that require navigation and interaction with page content.

Browserbase MCP is the hosted successor to the archived browserbase/mcp-server-browserbase project. Use it when the target workflow depends on Browserbase rather than a locally managed browser service.

How it works

An MCP client invokes Browserbase tools as the agent progresses through a browser task. The start operation creates a new Browserbase session or reuses an existing one. Once a session is available, the agent can move to a URL with navigate, perform page actions with act, inspect available interactions with observe, and retrieve page data with extract.

The end operation closes the current Browserbase session. Together, these operations provide a session-oriented workflow: start the browser, navigate and interact, inspect or extract information, then end the session.

Tools and capabilities

• start: Create or reuse a Browserbase session.
• end: Close the current Browserbase session.
• navigate: Open a URL in the browser.
• act: Perform an action on the current page.
• observe: Identify actionable elements on the page.
• extract: Extract data from the current page.

The combination of observe and act supports workflows where an agent first examines what can be interacted with, then performs an action. extract provides a separate operation for collecting information from the page after navigation or interaction.

Limitations and notes

Browserbase MCP is a hosted service rather than the archived self-hosted browserbase/mcp-server-browserbase implementation. Its documented scope is the Browserbase session and page workflow exposed through the six tools above: session management, navigation, actions, observation, and extraction. The server belongs in the browser automation category and is intended for agents that need access to a cloud browser through MCP.
